Self-starter adhesive and glue applicator



Apg. 14, 1962 x. l. SLOMON SELF'STARTER ADHESIVE AND GLUE APPLICATOR Filed April 14, 1960 JNVENTOR. IRA I S LO M ON BY A TTOP/VEV United States Patent 3,048,880 SELF-STARTER ADHESHVE AND GLUE APPLICATOR Ira I. Slomon, 36 E. 36th St., New York, N.Y. Filed Apr. 14, 1960, Ser. No. 22,313 3 Claims. (Cl. 15571) This invention concerns a new and improved applicator for adhesives such as liquid glue, rubber cement and the like.

A particular difficulty encountered with applicators for adhesives previously known has been the clogging or sealing of the orifices of the applicators after use making subsequent use difficult or impossible. Where rotatable members are employed in such applicators, they stick in their seats and cannot be rotated or removed.

The present invention is directed particularly at an improved adhesive applicator employing a roller in which there is provided a removable threaded shaft adapted to turn the roller to release it from the seat in which it may be stuck. The roller is generally cylindrical in form and has radial, threaded recesses which may be engaged by the threaded shaft for turning the roller if necessary. The seat for the roller is a flexible plastic member having a slot or a plurality of holes for passage of adhesive therethrough to the roller. The seat may be formed with a slot and recesses so that the roller can be adjustably seated. The slot permits the roller to be pried out of the seat without disengaging the shaft threaded therein.

It is therefore one object of the invention to provide an adhesive applicator including a plastic seat and roller, the roller being provided with a shaft for turning the roller out of a stuck position.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is an exploded perspective view of a container of adhesive with an applicator embodying the invention mounted thereon, parts being broken away.

FIG. 2 is a fragmentary sectional view on an enlarged scale of the container and applicator taken on line 2-2 of FIG. 1.

FIG. 3 is an elevational view of the seat portion of the applicator.

FIG. 4 is a top plan view of the seat portion of the applicator.

'FIG. 5 is a sectional view taken on line 5-5 of FIG. 4.

FIG. 6 is a perspective view of the roller per se.

FIG. 7 is a top plan view of another seat according to the invention.

FIG. 8 is a sectional view taken on line 88 of FIG. 7.

Referring to FIGS. 16, there is shown a cylindrical glass bottle 10 provided with a screw thread 12 for engaging a corresponding thread 14 in a cap 16. The bottle has a bead 18 at its open mouth under which may be engaged head 20 on the inside of an annular skirt 22. This skirt depends peripherally from a circular top 24 of a seat 25 forming part of the applicator embodying the invention. Upstanding from top 24 is a tubular neck 23 having curved end walls 26, 28 and curved side walls 30, 32. The side and end Walls are integral with an inner cylindrically curved partition 34 in which is a longitudinal slot 36 as clearly shown in FIGS. 2 and 4. The end wall 26 has a vertical slot 28 formed with opposed pairs of spaced recesses 37 and 38 and constrictions 39, 41. End wall 28 has spaced recesses 40, 42, one above the other. When the seat is mounted on the open top Cir "ice

of the container 10 as shown in FIGS. 1 and 2, a passage is provided for adhesive through slot 36 when the container and applicator are inverted.

A roller 50, which is generally cylindrical in form, is provided for seating in the neck 23. The roller has convex end walls 52, 5 4. End wall 52 has a threaded recess 55 adapted to receive the threaded end of a shaft 56. The shaft has a knob handle 58 to facilitate turning manually. The diameter of shaft 56 is equal to the maximum spacing in a horizontal direction of opposed recesses 37 and 38 parallel to top 24.

Radial recesses '60 threaded in the roller permit the shaft to be removed from recess 55 and threaded in any one of the circumferentially spaced recesses 60. A short tip 62 is provided at the axial end of the roller on wall 54. This tip may fit into either one of recesses 40, 42 in end wall 28 of the neck 23. The roller is preferably made of a rigid material such as plastic, ceramic, metal or the like. The seat 25 is made of resilient plastic material such as polyethylene so that the skirt 22 can be snapped over the bead 18 on the bottle. The neck 23 is also flexible so that the shaft 56 can be snapped past constriction 39 to engage in recesses 37 and past constriction 41 to engage in recesses 38. Tip '62 will then engage in recesses 40 or 42. Thus the roller is rotatable in either of two positions with respect to slot 36 so that the adhesive may flow less or more freely therethrough on to the roller for distribution thereby onto a surface to be pasted when the container and applicator are inverted. When the shaft is inserted in recess 55, the entire roller can be snapped out of the neck by pushing the handle upwardly parallel to the axis of the container.

In FIGS. 7 and 8, the seat 25 is shown modified by provision of holes 36* in partition 34 Only a single constriction 39 and a single pair of opposed recesses 37 are provided in end wall 26 to receive the shaft 55. Only a single recess 40 is provided in end wall 28 to receiver tip 62.

The invention thus insures that the roller can be readily released if it should become stuck in the seat due to the presence of residual adhesive after the container is placed upright following use. If the roller does not yield when the shaft is turned while threaded in the axial recess 55, then the shaft can be unthreaded and inserted in one of recesses 60 so that increased leverage is obtained for turning the roller to release it. There is always one or more of the recesses 60 sufiiciently free of adhesive to permit insertion of the shaft 56 therein. If the roller still is not released, then it can be pried out of the seat by pulling up on the shaft while it is threaded in any one of recesses 55 or 60. When the roller is thus removed, the interior of the neck can be cleaned of dried adhesive and the roller can be snapped back in position. The shaft 56 should be replaced in recess 55 in the roller.

It is to be understood that this arrangement may be provided for any type of container made of plastic, glass or any other suitable material. It may also be provided in the form of a collapsible tube for keeping liquid glue, rubber cement, polyvinyl acetate or other emulsions which includes my applicator release means.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent 1.
